# Troubleshooting
|
|
|
|
## `64 Bit Systems`
|
|
A 64 bit image can be generated from the `arm64` branch in this repository. Just
|
|
replace the command from [this section](#getting-started-with-building-your-images)
|
|
by the one below, and follow the rest of the documentation:
|
|
```bash
|
|
git clone --branch arm64 https://github.com/RPI-Distro/pi-gen.git
|
|
```
|
|
|
|
If you want to generate a 64 bits image from a Raspberry Pi running a 32 bits
|
|
version, you need to add `arm_64bit=1` to your `config.txt` file and reboot your
|
|
machine. This will restart your machine with a 64 bits kernel. This will only
|
|
work from a Raspberry Pi with a 64-bit capable processor (i.e. Raspberry Pi Zero
|
|
2, Raspberry Pi 3 or Raspberry Pi 4).
|
|
|
|
|
|
## `binfmt_misc`
|
|
|
|
Linux is able to execute binaries from other architectures, meaning that it should be
|
|
possible to make use of `pi-gen` on an x86_64 system, even though it will be running
|
|
ARM binaries. This requires support from the [`binfmt_misc`](https://en.wikipedia.org/wiki/Binfmt_misc)
|
|
kernel module.
|
|
|
|
You may see one of the following errors:
|
|
|
|
```
|
|
update-binfmts: warning: Couldn't load the binfmt_misc module.
|
|
```
|
|
```
|
|
W: Failure trying to run: chroot "/pi-gen/work/test/stage0/rootfs" /bin/true
|
|
and/or
|
|
chroot: failed to run command '/bin/true': Exec format error
|
|
```
|
|
|
|
To resolve this, ensure that the following files are available (install them if necessary):
|
|
|
|
```
|
|
/lib/modules/$(uname -r)/kernel/fs/binfmt_misc.ko
|
|
/usr/bin/qemu-aarch64-static
|
|
```
|
|
|
|
You may also need to load the module by hand - run `modprobe binfmt_misc`.
|
|
|
|
If you are using WSL to build you may have to enable the service `sudo update-binfmts --enable` |
